My invention relates to spudding shoes which are well known devices usedpreliminarily in the operation of drilling a well.

Well drillers find more or less difliculty, es-

gj pecially when spudding rapidly, in keeping the drilling cable inoperative connection with the spudding shoe due to the severe whippingor erratic swaying and jumping of the shoe, particularly whenever thedrilling 10 cable is fed out faster than the drilling tool progressesdownwardly. It is the principal object of this invention to providespudding shoes with safety features to prevent the drilling cables fromgetting out of their normal working positions in the shoes.

Referring to the accompanying drawings, Fig. 1 is a side elevation ofthe spudding shoe with portions of a drilling cable and a jerklinetherefor; Fig. 2, an enlarged side view of the shoe; Fig. 3, an endelevation of the shoe; and Fig. 4, a section on the line 4-4 on Fig. 2.

1 designates the body of the spudding shoe. The body has an arcuategroove or cable bearing 2 in one edge to receive the drilling cable 3,only a portion of which is shown. The groove may be in an integralportion of the body, but I prefer to have it in a liner 4 seated in thearcuate passage 5 in the shoe, the liner being held in the passage 5 bythe bolts 6.

An arm 7 projects outwardly from the arcuate side 8 of the body andpreferably at right angles thereto. It has at its free end the fork 9between whose members the roller 10 is mounted on the bolt 11 which actsas a pivot for the roller. 12 is a jerk-line of the ordinary kind havingthe eye 13 in which the roller 10 is positioned.

The arm 7 has its origin preferably midway between the ends of the body,the parts being arranged so that preferably the drill cable in thegroove 2 and the eye 13 include the same plane.

Between the fork 9 and the adjacent side 8 of the body 1 is theabutment, rib, or fin 14 which is separated from the side 8 by the space15 which is wide enough to permit the passage of the cable 3 into thegroove 2. The abutment rises from the face 16 of the arm 7 and lies atone side of the groove 2 and extends above the face 16 sufficiently farto assist in holding the cable in its normal place in. the groove 2.

There are two hooks 17, one between each end of the body 1 and itscentral portion. The hooks rise from that part of the body which isopposite the arm 7 or the face 16 and extend out beyond the side 8 ofthe body, the free ends being turned toward the plane including the face16 so as to over-lie the groove 2 and the part of the drilling cable 3therein and prevent the latter from jumping out of the groove.

The cable 3 is prevented from escape from the groove by means of theabutment 14 and the hooks 17, the abutment being carried by the shoe atone side thereof and the hooks being carried by the shoe at the otherside thereof. This abutment 14 need not be a narrow rib or fin as shown,it only being nec essary to have a space 15 whose length depends on thepredetermined thickness of the abutment 14.

The shoe has on one side a strengthening rib 18 and on the opposite sidethe rib 14 and the rib 19, the latter being on the same side of the shoeas the rib 14 and alined therewith. The opposing ends of the ribs 14 and19 are rounded to aid in guiding the cable to the space 15.

I claim:

1. A spudding shoe having a cable bearing and rigid hooks overlying thebearing at each side of the center thereof.

2. A spudding shoe having a cable bearing and rigid hooks overlying thebearing at each side of the center thereof, and an abutment lyingopposite the bearing and between the hooks.

3. A spudding shoe having a cable bearing in one edge, an arm projectingbeyond the said edge and adapted for connection to a jerk-line, anabutment positioned on the arm in front of the bearing and spacedtherefrom to provide for the entry of a drill cable to the bearing andmeans overlying the arm and spaced therefrom and from the abutment toconfine the cable in the space enclosed by the bearing, the abutment,the arm and the said means and to provide an ever-open path for passingthe cable laterally into and out of the said s ace.

4. spudding shoe having a cable bear- 5 ing in one edge, an armprojecting beyond the said edge and mrhzted for connection to ajerk-line, and fixed eoks carried by the body at the sides of theabutment and overlying I the bearing. i In testimony whereof, I hereuntoafl'lx my signature.
